IMPROVEMENT ,IN OIL-EJECTORS.

Specification forming part of Lettersl Patent No. 51,008, dated November21, 1865.

To all lwhom it 'may concern:

Be it known that I, REINHOLD BOEKLEN', of the cityof Brooklyn, in thecounty of Kings and State of New York, have invented a new Mode ofElevatiug Petroleum from its Wells; and 1 do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing, which represents a verticalcentral section of a well to which my device for elevating thepetroleumis applied.

.Similar letters of reference indicate corresponding parts in thedrawing.

The nature of my invention consists in an 'apparatus whereby thepetroleum is raised to a proper discharging-point upon a body of waterand against a body of air, and from this point discharged through a tubeof said apparatus at the top of the well.

One form of apparatus which is adapted for carrying out my invention mayconsist of two tubes, one within the other concentrically, the innertube having a weighted indicating-valve at its top, the outer tubeadmitting an influx of water, the inner an influx of air, until the oilin the Well rises above openings near thebottom of the central anddeepest tube, when the inux of air ceases and the continued inux ot'water through the outer tube, or the increase of oil in the well fromits surrounding sources, causes theoil to ascend through the centertube, and

by its pressure overcome the resistance ofthe graduated weight upon theYvalve, and thus expel all resisting air in the tube, and by iiowingthrough the valve-passage indicate to the superintendent that all isgoing on right, and that the escape or discharge cock ator near the ktopof the tube. should be opened.

t To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation.

Arepresents an oil-well; B, the mouth o r bore of the same.

Gis a tube, which is as large as the bore less the space required forit, to'be packed in the usual way with seed-bags, but with a great dealmore care, and as near as possible to the entrance into the well, in amanner to make an air-tight joint at the aforesaid place. This may-bedone by using a packing which may be expanded by means of havin g astuing-box Y connected with the top of the bore, or having an air-tightbag around the said tube C, which may be expanded by charging the samewithcompressed air or water.'

D is an air-tube, and is within the tube C. E is a pipe provided withastop-cock, F, and

connected with au air-pump. G is a stop-cock,

also connected with the air-tube D.

H is an air-valve on the top of the tube D, and is held to its seat by alever, I, and weight J, the said lever being marked to indicate thepressure against the valve in pounds or otherwise; but the valve is madein a manner that it can be removed.

K is a water-reservoir connected with a pump by a pipe, L, and connectedwith the tube C by a stop-cock, M. l

The operation upon the well is as follows: The dept-h of the well is rstdetermined prop- "e'rlyand from this is calculated the necessarypressure to raise a column of oil from it to the top of the tube D. Theapparatus is then set ready for operation, all the stop-cocks closed,and the weight J placed on the lever I to press on the valve H with apressure equal to raise the oil in the tube D corresponding with thecalculation made before. Now the air-pump is set to work and thestop-cook F opened and the air compressed in the well until the Weight Jis raised. Then the cock F is closed and the air-pump stopped, the cockM opened and the water-pump set in motion, whereby the Water from thereservoir K tlows down to the bottom of the well and gradually raisesthe oil until the same appears coming out through the valve H, at whichtime the cock Gr is opened and the pressure in the tube D entirelyremoved, whereby the oil will flow freely off the cock G. The watershould not be supplied any faster to the well than the oil escapes fromit, and the valve H should be carefullyY watched so as not to be loadedtoo little or too much before the oil is coming to it.

`From the foregoing the mode of raisin g 1n ay be clearly perceived. Thecompressed air has to take the place of the gases usually contained` inthe well when the operating 'is first begun, and the water-pressure isused toelevate the oil and to take the place of the oil formerlycontainedin it.

What I claim as my invention, and desire to secure by Letters Patent,is-
